Grader :                    Wanning Li,

Course Goal:         To provide each student with the ability to model, analyze, operate and design electric transmission systems.

Course Pre- and Co-requisite: EE 303, Credit or Registration in EE 324

Required Student Materials: The required textbook is below:


Book Title


Power System Analysis

Book Author


Bergen & Vittal

Book Edition



Book Year



Book Publisher


Prentice Hall



Power system operations; automatic generation control, electricity markets, and ancillary services; influence of storage; power system protection,

symmetrical components, faults, stability.

Course objectives: 

Objective 1


Understand the operation of the power system in terms of frequency regulation and real-time markets.

Objective 2


Analyze unbalanced power systems using symmetrical components.

Objective 3


Perform fault analysis using symmetrical components and determine fault currents and voltages at various locations in the network.

Objective 4


Utilize the philosophy and the principles underlying power system protection; to set primary protection and back-up protection for inverse time overcurrent relays.

Objective 5


Articulate the principles of transient stability assessment in power systems, and perform analysis of transient stability using the equal area criterion for the one machine-to-infinite bus system.

Objective 6


Incorporate short circuit analysis and transient stability analysis into the design of a transmission addition to a power system


Exams: There will be 2 closed notes exams and an open notes final exam. Make-ups will be given only for extenuating circumstances outside the control of the student, and arrangements MUST be made in advance of the regularly scheduled exam. Exams dates are given on the schedule. It is your responsibility to know exam dates.

Assignments: Homework assignments will be made regularly and submitted for grade. The grader may check one or all problems or any number in between to assign your HW grade. Solutions will be provided and posted on the website. The grader is not responsible to correct your assignments; rather, you are responsible to review the solutions and ensure that you did in fact solve each problem correctly.

Course project: You will be assigned a course project where you will need to perform power system fault analysis, protection design, and stability analysis.

Class Attendance: You are strongly encouraged to attend class. Some material may be presented that is not in the notes on the Website. You are responsible for this material. In addition, a significant amount of learning will occur in class; you will learn less efficiently if you attempt to cover the material without the in-class instruction.

Class Preparation: Reading and studying the scheduled material in the text in advance of the class will be essential. Brining your laptop to class is wise, because then you can follow the notes. Bringing a hardcopy of the notes to class is wiser because then you can make annotations on them to remind you of what was discussed in class. A schedule of topics is given on the website.

Communication: Feel free to communicate with me in any way that is convenient to you (after class, during office hours, phone, e-mail), for questions about the course material or assignments. E-mail is an especially good way, but response time here is variable, typically ranging from a minute to about 24 hours, depending on the nature of your question and my schedule.


Students with Disabilities

Iowa State University is committed to assuring that all educational activities are free from discrimination and harassment based on disability status. All students requesting accommodations are required to meet with staff in Student Disability Resources (SDR) to establish eligibility.  A Student Academic Accommodation Request (SAAR) form will be provided to eligible students. The provision of reasonable accommodations in this course will be arranged after timely delivery of the SAAR form to the instructor.  Students are encouraged to deliver completed SAAR forms as early in the semester as possible.  SDR, a unit in the Dean of Students Office, is located in room 1076, Student Services Building or online at  Contact SDR by e-mail at or by phone at 515-294-7220 for additional information.
